| Hogaamiye-mw | Hordhac Ultra Wideband Omnidirectional Antenna |
Soo bandhigida hogaamiyaha tignoolajiyada microwave., (hogaamiyaha-mw) anteeno dhan walba ah oo ultra-wideband ah oo cusub ANT0104. Anteenadan xoogga badan waxaa loogu talagalay inay ku shaqeyso inta u dhexeysa 20MHz ilaa 3000MHz, taasoo ka dhigaysa mid ku habboon codsiyada kala duwan oo ay ku jiraan isgaarsiinta wireless-ka, nidaamyada radar iyo kuwo kale.
Faa'iidada ugu badan ee anteenadani way ka weyn tahay 0dB, iyo leexashada ugu badan ee wareega waa ± 1.5dB, hubinta la isku halayn karo iyo gudbinta signalada joogtada ah. Waxqabadkeeda waxaa lagu sii xoojiyay ± 1.0dB qaabka shucaaca toosan, oo siinaya dabool heer sare ah dhammaan jihooyinka.
ANT0104 waxay leedahay sifooyin toosan oo toosan, taasoo ka dhigaysa mid ku habboon codsiyada halka gudbinta tooska ah la doorbido. Intaa waxaa dheer, anteenada VSWR ≤2.5: 1 iyo 50 ohm impedance waxay bixiyaan isbarbardhigga ugu fiican iyo luminta calaamadda ugu yar.
Naqshadaynteeda cufan iyo qallafsan ayaa ka dhigaysa mid ku habboon isticmaalka gudaha iyo dibaddaba, iyo hawlqabadkeeda jiho kasta waxay u oggolaanaysaa isku-xidhnaan la'aan deegaan kasta.
Haddii aad u baahan tahay inaad kordhiso xoogga signalada shabakadaada wireless, kor u qaado waxqabadka nidaamkaaga radar, ama aad si fudud u rabto inaad hubiso isgaarsiin la isku halayn karo oo baaxad leh, ANT0104 Ultra Wideband Omnidirectional Antenna waa xalka ugu fiican.

Qiyaasta la taaban karo ee iskudarka toosnaanta anteenada D, waxaan ku qeexnay cabbirka kala duwanaanshaha shucaaca anteenada.
Tilmaamaha D waa saamiga ugu badan ee cufnaanta shucaaca P(θ,φ) Max ilaa qiimihiisu celceliska P(θ,φ)av ee goob ku taal gobolka fog-fog, waana saami aan cabbir lahayn oo ka weyn ama le'eg 1 Habka xisaabinta waa sida soo socota:
Intaa waxaa dheer, jiheynta D waxaa lagu xisaabin karaa qaacidooyinka soo socda:
D = 4 PI / Ω _A
Ficil ahaan, xisaabinta logarithmic ee D waxaa badanaa loo adeegsadaa si loo matalo faa'iidada jihada ee anteenada:
D = 10 log d
Jihaynta sare ee D waxaa loo tarjumi karaa sida saamiga kala duwanaanshaha xajmiga (4π rad²) antenna beam range ω _A. Tusaale ahaan, haddii anteenadu u soo ifbaxdo oo keliya cirifka sare ee hemispherical oo kala duwanaanshihiisa uu yahay ω _A=2π rad², markaa jihayntiisu waa:
Haddii logarithm-ka labada dhinac ee isla'egta kore la qaato, faa'iidada jihada anteenada ee la xiriirta isotropy waa la heli karaa. Waa in la ogaadaa in faa'iidadani ay ka tarjumayso kaliya shucaaca qaabka jihada anteenada, oo ah unugga dBi, maadaama waxtarka gudbinta aan loo tixgelinin faa'iidada ugu habboon. Natiijooyinka xisaabinta waa sida soo socota:
3.01 fasalka: dBi d = 10 log 2 qalab
Unugyada faa'iidada anteenada waa dBi iyo dBd, halkaasoo:
DBi: waa faa'iidada laga helo shucaaca anteenada marka loo eego isha dhibicda, sababtoo ah isha dhibicdu waxay leedahay ω _A=4π faa'iidada jihaduna waa 0dB;
DBd: waa faa'iidada shucaaca anteenada marka loo eego anteenada dipole badhkeed;
Qaabka beddelka u dhexeeya dBi iyo dBd waa:
2.15 fasalka: dBi 0 DBD wax
